Student Outcomes

Students understand that each nonzero integer, a, has an opposite, denoted -a; and that -a and a are opposites if they are on opposite sides of zero and are the same distance from zero on the number line.

Students recognize the number zero is its own opposite.

Students understand that since all counting numbers are positive, it is not necessary to indicate such with a plus sign.
